Methods:Thirty-two
keratoconus suspects and 36 healthy eyes were selected within the age range of
20-30 yrs. Their pachymetry pattern was obtained through OCT Visante in the
minimum thickness spot, upper and lower corneal difference (I-S), lower
temporal, and upper nasal thickness (IT-SN), withdrawal or non-withdrawal of
the minimum thickness area of cornea from 0-2 central zone using the output
map.

Results: In all measured
parameters a significant difference was observed between the two groups
(p<0.0001). The Keratoconus suspects had a thinner cornea and showed more
changes in corneal thickness than the normal group.

Conclusion: It seems that an OCT
system of anterior segment can be utilized to assess patients prior to
refractive surgery or Keratoconus screening, along with equipments such as
Pentacam, and Orbscan.
